$= ( - 3 - 4 - 12) + (7 + 9)$

$= - 19 + 16$

$= - 3$

$= ( - 5 - 8 - 10) + 23$

$= - 23 + 23$

zzz [600]

Answer:

Step-by-step explanation:

To find s4 we find sum of values when n=1,n=2,n=3,n=4

given expression is $6(2)^{n-1}$

n=1 , plug in 1 for n

$6(2)^{1-1}=6$

n=2

$6(2)^{2-1}=12$

n=3

$6(2)^{3-1}=24$

n=4

$6(2)^{4-1}=48$

Sum of all 4 terms = 6+12+24+48=90
